LSISAS6160 SAS Switch User GuideChapter 2: Installation and Hardware Setup | Installing the SAS6160 Switch
2.2.1 SAS6160 Connectors All 16 connectors on the SAS6160 switch accept standard passive SAS cabling. The
connectors at port 0 and port 2 are active, which allows longer cable lengths when
using active SAS cabling. See Chapter 1 for an explanation of SAS connectors and
cables.
2.2.2 SAS6160 LEDs The following table shows how to interpret the LEDs for the system, the phys, the
power supply module, and the Ethernet (RJ-45) connector. The LEDs in the RJ-45
connector are built into the left and right corners of the connector.
2.3 Installing the SAS6160 SwitchWARNIN G: To prevent the SAS6160 switch from overheating, do not operate it in an
environment that exceeds the maximum recommended ambient temperature of 50ºC
(122ºF).
When installing the switch, consider the following information:
The acceptable temperature and humidity operating ranges for installation and
operation of the switch are as follows:
— Temperature Range: 5–50 ºC (dry bulb)
— Relative Humidity Range: 5%–90% noncondensing
— Maximum Dew Point Temperature: 32 ºC
Install the SAS6160 switch in a site free from strong electromagnetic field
generators (such as motors), vibration, and dust.
Allow some space at the back of the switch (where the fans intake air) for proper
ventilation.
The AC power adapter is rated at 100 V to 240 V, and 50 Hz to 60 Hz.
